Which of the following options correctly describes the classification of Lists?

The correct choice points to the fact that to enable end-users to define their own classification criteria within Lists, other widgets must be employed. In practical applications, Lists on their own offer a simple display of data but lack advanced capabilities for dynamic user input concerning sorting or filtering.

If we consider the role of additional widgets, they are often designed to facilitate interactions such as dropdowns, search fields, or sliders that allow users to specify how they want to classify or filter the data presented in the list. By using these supporting elements, developers can create a more interactive and customizable user experience.

The options that describe other aspects of Lists instead emphasize limitations or functionalities that aren't aligned with this interactive capability. For example, the notion of an integrated On Sort event directly pertains to the list's internal functionalities rather than user-driven input. Similarly, the inability to change classification clauses dynamically at runtime undermines the flexibility that users would expect when working with Lists. Lastly, stating that Lists cannot be classified at all overlooks their inherent capability to display ordered or filtered data when properly structured, which further highlights the importance of employing additional tools for user-driven classification.
